Regarding quick & convenient modern component testing. I suggest this
item which I and several others I know (net 200 years electronic
experience) have built and are full of praise for!

I sprung for one of these on the strength of your report. I'd been
watching many auctions of similar things, but most ship from China. It's
inexpensive (below my what-the-heck threshhold) and can ship from US.
Got here yesterday.

Took me all afternoon (not an hour like some of you wizards) to build,
partly because my hands are not as steady as they used to be, partly
because these parts are getting smaller, and partly because the last kit
I built was a Heathkit.

Only one problem with the kit. The 28-pin DIP socket had lost three
pins. Two were loose in the bag and I put them back, but I didn't have
any like them and one pin short just won't do. I grabbed a 20-pin and
an 8-pin out of my thirty-year-old stock and used them.

Seems to work just fine (resistance reads a little high, somewhere
around 1%). I might want it to be a voltmeter and/or a frequency
counter as well, but it's just a device for passive parts. Even so, I
have one item for that wish list: If I stick a crystal in, tell me its
frequency.

Some fine-tuning I'd like someone else to do... Use the classic
triangle-wave symbol for a resistor. Curve one of the lines in the
capacitor symbol and indicate appropriate polarity.

I'm not sure how much I want to tighten and loosen those screws in the
test fixture. I suppose it would be simple enough to wire up an
outboard ZIF socket there.

Sorry, meant the Amperite part#, looking to source a replacement. Similar part died on my 545a some 20+ years ago. I ended up (non destructively) sticking a damn button of the side of the unit to short the contacts.

I'm not honking, but the Tek part number for that relay is 148-006 (so
probably 148-0006-00).

Honk! triggers from 'cal' on 'A' channel only, but it's a start. Needs a new thermal delay relay too - got a part # on that btw?

Honk if you have a working 661. (Kurt honks)

Interesting. Now that you got me thinking about it, I noticed one other important difference: The original CRT has a round CRT in the logo, and the replacement has a square CRT in the logo (confirming my suspicion that the replacement is newer).
I didn't see those markings echoed anywhere else on the tube, but there is an embossed label toward the front of the CRT (visible only when removed).
Old = '12 A 5'
New = '503 B 59'

Anyone know when the official logo cross-over happened?

PS - I just got first trace on a 661. Totally unrelated, just braggin'

Hi Paul,

You mention the difference in CRT slide pads (6 versus 5) while the part numbers are the same 154-0410-00. I don't remember the layout of my 564 CRTs and it's not visible when the CRT is installed. I only inspected some yellow labels, 2 x 564 and 1 x 564B. Non of these show the type number T5640-200 or T5641-200. Maybe a separate label somehere? There is an "artists impression" of the 564 (I think) CRT at the first page of the 1963 catalog, ressembling your old CRT. At internet I saw photo's of the 564B CRT still having six contacts.

Albert

Alan,

This looks like it would be very handy to have. When you have a chance to
use it we will all be interested in how well it works, and what, if any,
drawbacks it has.

Thanks, Dennis Tillman W7PF

this is a very late digital scope, with multiplexed front panel controls, and 4 vertical channels. I have (incredibly) the tek user manual, but what I NEED is a cal manual, as this unit is out of calibration. It's very handy (although not too fast), so I'd like to hang onto it for bench use here, but I really need to adjust it properly, right now I have about a 20% vertical deflection error. very annoying.

it is surprisingly noisy in the digital mode, but does have print capability, store and reference and lot of nice features. the fan is noisy, that I have to fix. weirdly, it is the only Tek scope I have seen that DOES NOT have a lighted graticule, even though the CRT has one.

anybody that has a service manual or cal instructions, I would really like to hear from you! it is not like the 2214 at all, so that unit won't help. nothing on the tek site, and the only document I have found on the web is the same user manual I already have. rats!

all help appreciated!

Newer systems use a recovery partition instead of a CD or DVD. But you can
make a bootable USB flash drive from the recovery partition, and you should
do that in case your hard drive fails. Windows will nag you periodically to
make one.

We have a Dell desktop at home too that recently had the hard disk

with install/recovery disks, but _did_ send them to us after we called
them and insisted. We now have the proper disks to reinstall onto the

Anyone with a Dell without these disks should call Dell and insist
that they be sent to you! Sooner or later, you'll need them.

Bob,
I think that I may have a Dell recovery disk. If I do I can make a
copy and send it to you. It will only work on a genuine Dell computer.
There is a hidden partition on the hard drive with the OS and other
programs files in a compressed format located on it. The recovery disk
accesses that partition and re-installs the OS off of the partition.
The sticker is required by MS and it is about piracy but from MS
and not from Dell. I don't like not having an actual OS disk and then
additional disks with their programs on them but Dell would have to had
sent several disks with their computers. Their setup allows the computer
to be connected to a network and all of this done with scripts by just
one or two people doing a thousand computers at one time. When I do
a reinstall I have to be near by to push buttons and keys. It takes
hours for me to restore just one computer. In fact I can restore ten
computers almost as fast as I can do one computer. From Dells end it is
about profit but not in the way that you are thinking about.
Thanks,
rich!

Hey Albert - just to close the topic, I checked V800 screen voltage with the CRT removed and it was right around 65v
I sourced a replacement CRT and that ended up solving the problem (chronicled here ) Thanks!

Hi to All,

Just outbidded on a set of four on these :<(. Nevertheless I am still interested in how it works? My Manual Vendors have no Manual on this one (SI5020 and AT5010 Manuals no problem). The SCALCF1 was part of the SCAL102 ScopeCal System (page 369 1993 Product Catalog) and was GPIB Programmable. Its Front has some similarities with another Calibration Fixture: the 067-0184-00. This last one was not GPIB Programmable and pictures of it can be seen on one of Yahoos Photoalbums. Maybe the 067-184-00 Fixture was used to calibrate SCALCF1's. Any suggestions or insight information on these?

Greetings,

Egge Siert

I bought mine for 80 euro's at the largest electronics fair in the Netherlands. It was 120, but nobody wanted it. At the end i offered 80 and that was accepted. Came with a new matching probe too :). It missed some buttons and one of the input attenuators was toast. Got the attenuator and replaced all caps. Instead of finding buttons, i bought the whole pannel with the buttons from a supplier in Israel. Obviously somebody missed the that part with the hammer...

Still have the old pannel and it has the three largest buttons. The sec/dev is not completely straight, but usable. Give a shout on what you find.

I was going to use this website for a project I haven't done yet, so it is set up for ordering whatever CRTs I acquired recently.

**Please do all correspondence through that site. Of course any scopes you bring back to life would be fun to hear about here.

Thanks,
Bob
